Quadrilateral JKLM has side lengths of JK = 2y + 3, KL = 8x – 10, LM = 5y – 6, and JM = 3x + 20. Find the values of x and y that make quadrilateral JKLM a parallelogram. A. X = 6, y = 6 B. X = 6, y = 3 C. X = 13, y = 3 D. X = 2, y = 1
Answers
Answer:
(6, 3)
Step-by-step explanation:
Note that the opposite side of parallelogram are congruent, hence;
Jk = LM
2y + 3 = 5y - 6
2y - 5y =-6 - 3
-3y = -9
y = 9/3
y = 3
Similarly;
KL = JM
8x – 10 = 3x+20
8x - 3x = 20 + 10
5x = 30
x = 30/5
x = 6
Hence (x,y) is (6, 3)

The sum of the interior angles of the 10-sided polygon on the left is °
Answers
Answer:
1440 it is right because
Step-by-step explanation:
Decagon is a 10-sided polygon.
Formula to find the sum of interior angles of a n-sided polygon is
= (n - 2) ⋅ 180°
By using the formula, sum of the interior angles of the given decagon (10-sided polygon) is
= (10 - 2) ⋅ 180°
= 8 ⋅ 180°
= 1440°

Step-by-step explanation:
(I'm not sure if the two equations were the same or not, but I provided the answers just in case.) Parallel lines are two lines that have the same plane and slope but never intersect. To find the equation, use the formula y - [tex]y_{1}[/tex] = m (x - [tex]x_{1}[/tex])
